Glossary Numerology

Hereditary number

The hereditary number is calculated from the letters of the surname alone. Each letter receives its value from 1 to 9 in the Pythagorean table, and the sum is reduced to a single digit. It describes the family inheritance carried by the family name: the traits, resources and patterns passed down through the lineage. Paired with the active number drawn from the given name, it completes the expression number of the full name.

What it carries of you

Your hereditary number speaks of what you receive before you choose: the thread of your lineage, the strengths and habits written into your surname. It is not a fate, more a backdrop. Recognizing it means weighing what you were given, so you can then decide what you want to keep and pass on.

How to work it out

Write your surname, give each letter its value in the Pythagorean table, add them and reduce to a digit from 1 to 9. Set it beside your active number, drawn from the given name: one tells your personal drive, the other your inheritance. Their sum, reduced, joins your expression number and closes the reading of the full name.
